METHOD OF AND DEVICE FOR CLEANING PLENUM AIR Russian patent published in 2003 - IPC

FIELD: air cleaning. SUBSTANCE: invention relates to domestic air cleaners and methods of cleaning of air and its deodorization. It can be used in dwelling housing, hospitals, laboratories, transport and everwhere where high degree of air cleaning is required. According to proposed method air flow is formed and force directed as required. Prior to air delivery, large dispersed particles are removed from air and then air is subjected to treatment with electrostatic field and conditions are provided to exclude getting of precipitation into air flow. After treatment with electrostatic field, air flow is subjected to process of absorption and decomposition of gas admixtures with maintaining optimum cleaning conditions by means of primary converters and control elements basing on whose readings cleanness of air getting into room is judge. Device contains housing accommodating series-mounted entrapping, settling and absorbing filtering elements and electric fan, precipitation protection unit, decomposition filtering element, primary converters and control signal shaper and control unit. EFFECT: improved efficiency of air cleaning, operation reliability, reduced cost and mass and dimensions. 12 cl, 1 dwg
